Answer: x = -29
Step-by-step explanation:
-0.59x+0.39x=5.8
Collect like terms
-0.2x = 5.8
Divide both sides of the equation by -0.2
x = -29
Response to user in comments:
-0.59+0.39=-0.2 that is a fact
-0.2/-0.2=1 that is a fact
5.8/-0.2= - 29 that is a fact
These are the facts about the steps of the equation. Solving Steps for Solving the Equation

Answer:
(-3,4)
Step-by-step explanation:
x + 2y = 5
-3 + (2*4) = 5
-3 + 8 = 5
5 = 5
2x + 3y = 6
(2*-3) + (3*4)=6
-6 + 12 = 6
6 = 6
Answer:
(-3,4)......... multiply the first equation by the coefficient of y i.e 3 (of 2nd equation)...
again multipy the 2nd eq by the coefficient of y i.e 2 (of 1st eq)
and finally solve the eq 3 and 4 ...(solve the both eq formed by multiplying)

Given that sin θ = 3/4 and θ is in Quadrant II:
Find cos θ.
this is for the Sin
*Remember that sin = opposite / hypotenuse*
a² + b² = c² (where a and b are legs and c is the hypotenuse)
From the picture, you can see:
a = 3
c = 4
Plug these into the equation and solve for b.
* a² + b² = c² *
step 1: 3² + b² = 4²
step 2: 9 + b² = 16
step 3: b² = 16 - 9
step 4: b² = 7
step 5: √(b²) = √7
step 6: b = ± √7
FOR COS:
From the picture, you can see that if θ is in quadrant II, b has to be negative.
b = -√7 = adjacent
Remember that cos θ = adjacent / hypotenuse.
cos θ = adjacent / hypotenuse
cos θ = (-√7 / 4)

select all the figures with 180° rotation symmetry.
A. image A: right, isosceles triangle
B. Image B: rectangle
C. Image C: square
D. Image D: regular pentagon
E. Image E: regular hexagon
plz help me
A figure with a rotation symmetry will look the same, when rotated. The figures with [tex]180^o[/tex] rotation symmetry are:
B: rectangle
C: square
E: regular hexagon
For a shape to have a [tex]180^o[/tex] rotation symmetry, the following must be true.
The shape must have an even number of sides (4,6...)The shape must have equal and parallel opposite sides.Options (a) and (d) do not meet any of the above conditions.
However, the stated conditions are true for options (b), (c) and (e); because they have parallel & equal opposite sides; and they have an even number of sides.
Hence, the rectangle, the square and the regular hexagon have a [tex]180^o[/tex] rotation symmetry
See attachment for an illustration of rotation symmetry.

If the volume of a cube is 1,728 cubic inches, find the side length of each of its sides
Answer:
12 inches
Step-by-step explanation:
Since we know that a cube has all equal length slides, and since we are given the volume, we can just simply find the cube root of 1728 to find the length of each side of the cube.
∛1728
= 12
The side lengths of the cube are each 12 inches long.

Find the sum and the product of the roots of the equation: x^2+35x−51=0
what is the product of them?
Answer:
(a)
[tex]Sum = -35[/tex]
[tex]Product = -51[/tex]
(b)
[tex]Product = 1785[/tex]
Step-by-step explanation:
Given
[tex]x^2 + 35x - 51 = 0[/tex]
Required
(a) Determine the sum and product of the equation
(b) Determine the products of the (a)
Solving (a)
The general form of a quadratic equation is:
[tex]ax^2 + bx + c = 0[/tex]
Where
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Product = \frac{c}{a}[/tex]
By comparison of [tex]ax^2 + bx + c = 0[/tex] tp [tex]x^2 + 35x - 51 = 0[/tex]
[tex]a = 1[/tex]
[tex]b = 35[/tex]
[tex]c = -51[/tex]
So:
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Sum = -\frac{35}{1}[/tex]
[tex]Sum = -35[/tex]
[tex]Product = \frac{c}{a}[/tex]
[tex]Product = \frac{-51}{1}[/tex]
[tex]Product = -51[/tex]
Solving (b)
From (a) above, we have:
[tex]Sum = -35[/tex]
[tex]Product = -51[/tex]
Their product is:
[tex]Product = -35 * -51[/tex]
[tex]Product = 1785[/tex]
